SAFE-DOOR.

SPECIFICATION forming part of Letters Patent No. 289,124, dated November27, 1883,

Application filed September 7, 1883. (No model.)

.To all whom it may concern-.-

Be it known that I, MosEs MosLnR, a citizen of the United States,residing at Cincinnati, county of Hamilton, State of Ohio, have inventedcertain new and useful Improvements in Doors for Fire-Proof Safes, ofwhich the following is a specification.

This invention is an improvement in fireproof-safe doors, such as shownin my application for patent filed February 10, 1883. Its object is tocheapen the construction therein shown and prevent the liability of theframe to warp or get out of shape in molding. Its object-is also toprovide for filling the door from the back, so that it may be finishedbefore the filling is put in which makes it u11- wieldy. I

With these objects in view my invention consists in casting the chamberfor the lock and bolt work with the front flange or edge of thedoor-frame, leaving the portion of the door back of it an open frame,and providing a loose plate to snugly fit within the opening, so thatwhen in place it forms the back of the door, leaving the lock and boltwork exposed, so that they are readily accessible for removal or repairs without disturbing the other parts of the door.

In the accompanying drawings, forming part of this specification, Figure1 is an inside plan View of a door embodying my improvements. The backplate, which covers the fireproof filling, is shown removed, and isrepresented in Fig. 3. The lock and bolt work are also shown removed, asthese may be of any approved construction. Fig. 2 is a transversesection of the door, taken through line 00 x of Fig. 1.

The door-frame A 'is of the ordinary construction, except that it hascast with its front edge or flange a shallow chamber, B, to receive thelock and bolt work. The walls of this chamber come flush with the inneredge of the door-frame. From the edge of the doorframe and the walls ofchamber B project in- 5 wardly lugs b, to form bearings, upon whichrests the back plate, 0, its outer side coming flush with the edges ofthe door-flanges. The inner wall of chamber B has bosses b cast with it,which are drilled into from the edge of the door to form pockets for thereception of the inner ends of the front-edge bolts. There are also lugsI) cast upon the bottom of chamber B, which are drilled from the top andbottom edges of the door, to furnish bearings for the x top and bottomedge bolts.

I have shown between the front plate, D, which is of ordinaryconstruction, and the bot tom of chamber B (see Fig. 2) two forms ofbearings for the lock and bolt spindles. One form, E, being cast in onepiece with the chamber B, and the other, E, being in the form of ahollow stay-brace. \Vith either form the arbors, lock, and bolt work areentirely isolated from the fireproof filling, and will therefore not becorroded or injured by the acid or moisture given off the cement.

I do not broadly claim herein a safe-door back east in'one piece withthe side flanges, and having a depression in its face for the receptionof the lock and bolt work, as that is the subject of my said pendingapplication.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

In a door for fire-proof safes, the combination, as specified, of thehollow frame A and the chamber B, cast with and forming part of saidframe, with the removable plate to close the space in the rear portionof the frame, the walls of said chamber B coming flush with the innerface of the door, and having lugs b around it and the inside of thedoor-frame to form bearings for the said back plate, 0.
